The extent to which Covid-19 has affected schools across England is shown in new data compiled by Tes today.
Figures provided by 62 education authorities across England reveal a big disparity in the proportion of schools in different areas that have had pupils or staff test positive for coronavirus.
In total, at least one in three schools have had Covid cases this term, across the areas that provided figures.
Tes asked all local authorities across England how many schools in their area have had Covid cases since the start of term.
Sixty-two councils covering all nine government regions responded.
The figures provided are below. Some authorities have only provided figures for September, so the number and proportion of schools with Covid cases in these areas are now likely to be higher.
